Gillian MacLellan is a partner in our UK Employment Team working with clients in various sectors across the UK, advising on both contentious employment matters and transactional work; the common thread in both areas is her ability and determination to get a great result for her client. Gillian works regularly with clients in the financial services and energy sectors where her industry experience ensures her advice is well rounded and fit for purpose. Gillian frequently advises clients with a global footprint meaning she has strong experience of the challenges for international employers, both from a compliance and a culture perspective. An area of keen interest for Gillian is supporting on diversity & inclusion and in this space, by way of example, she has worked with employers on global diversity reviews, advised on the roll out of D&I reporting projects and supported employers on complex internal harassment complaints as well as defending discrimination claims before the Employment Tribunal.

Gillian is a regular speaker at conferences and an author for LexisNexis and XpertHR. She also writes monthly for The Herald on issues of interest to employers.

The Law and the Little Things: Mi­cro­ag­gres­sions in the work­place
Mi­cro­ag­gres­sions in the work­place Most or­gan­isa­tions today re­cog­nise the im­port­ance of equity, di­versity and in­clu­sion with­in their work­places, in par­tic­u­lar, how to build an in­clus­ive cul­ture.  However, or­gan­isa­tions need to go bey­ond warm words to de­liv­er on com­mit­ments in prac­tice. Mi­cro­ag­gres­sions are subtle acts of dis­crim­in­a­tion; un­for­tu­nately com­mon­place be­ha­viours that many write off as too trivi­al to men­tion - the “little things” that just hap­pen. Though “little” in name, these oc­cur­rences can be­come large by nature, and busi­nesses must be aware of the deep and of­ten dev­ast­at­ing im­pact of ig­nor­ing them.

Ex­ec­ut­ive Re­mu­ner­a­tion
Link­ing ESG out­comes to ex­ec­ut­ive pay is now wide­spread, as com­pan­ies use their re­ward struc­tures to hold seni­or lead­ers to ac­count for their sus­tain­ab­il­ity ini­ti­at­ives.  Ac­cord­ing to re­cent re­search three in five FTSE 100 ex­ec­ut­ive bo­nus plans now have an ESG com­pon­ent. The move to­wards great­er sus­tain­ab­il­ity is driv­en by a range of factors; not only are in­vestors and the gen­er­al pub­lic in­ter­ested in this is­sue, but new reg­u­la­tion and cor­por­ate gov­ernance stand­ards play a role here too. It’s not all plain sail­ing. One of the chal­lenges with ESG is ac­cur­ately meas­ur­ing and bench­mark­ing stand­ards, and this is a key is­sue when draft­ing ESG pay and bo­nus re­lated con­di­tions. Em­ploy­ers should take ad­vice be­fore draft­ing these pro­vi­sions to un­der­stand what they need to do in re­la­tion to:leg­al and reg­u­lat­ory con­sid­er­a­tion­show their ex­ec­ut­ive re­mu­ner­a­tion pro­vi­sions fit with their long term ESG strategythe evolving ESG land­scape and fu­ture proof­ing their ap­proach share­hold­er and in­vestor views sec­tor/mar­ket prac­tice
