At work we are having a day in July were we are going to a team building day. Everyone has to go and there are about 120 of us in the organisation. There have been t-shirts ordered for us all to wear on this staff day but the largest they ordered is a large which just about fits my size 16 colleague. I am a few sizes (and the rest!!!) bigger than her and there is no way my rolls of bulge will fit into one. I spoke to HR who ordered them to explain my predicament and they said the company they order from only goes up to a large and that i'll just have to wear my own clothes. Now, my colleagues (well, my female ones) are all slender or under a size 16 I would guess by looking at them and I will be the only woman not able to wear a tshirt. There are a few larger male colleagues, but I will feel embarassed at being 'different' than my female co-workers. Is this unfair, or should I shut up and do something about my weight so this doesn't happen in the future?
