Almost every process has inefficiency and unnecessary elements which can be highlighted if studied well enough, removing those will improve productivity. A different option would be to consider if everything done is absolutely critical. You could say rank every task A to D in terms of priority and where Ds are nice to haves, admit they won't be done. I get the tea break issue though and although you'd think a four day week might be taken up by companies who are concerned for employees welfare, there's those who may do it to primarily to reduce overheads? Either way, if not well managed, could be problematic for those already overworked, stressed, under supported.
