Weinberg said, according to The Telegraph: "If you've grown up in a world where social media is at your fingertips and those kinds of social judgments are being made fairly constantly, suddenly you're even more aware of what others might be thinking.
"Naturally that's going to spill over into all kinds of areas, particularly something that can be a social taboo when you think about maybe not giving, or maybe questioning why people are giving.
"I think there can be a bit of that and naturally it does lead to anxiety for a lot of people."
He also claims exchanging gifts has added major anxiety to younger people who fear their presents won't be well received.
Weinberg hopes offices will prioritise wellbeing over presents.
One in five workers believe birthday and Secret Santa presents should not be celebrated in the workplace and 35 per cent of millennials surveryed would like to see them banned.
