I'm a senior PA to an extremely busy London Chief Executive who relies on me for everything. I hardly ever take sick days and even went into work every day when I broke my wrist! Although I've only had to take one day off in the last 13 weeks I'm finding the job increasingly tiring, and I'd like to have the pregnancy out in the open in the faint hope that colleagues might not expect so much of me. The trouble is I just don't know how to tell the boss because I don't think he'll take it well. Finding cover will be stressful for him and to make matters worse his mother died last week so my timing is terrible. Although this is my first baby I've already got a bump and don't know how much longer baggy tops are going to keep it hidden. I'm interested to know how other people told their bosses and what ther reactions were. Thanks.
