Why continuity matters more than it appears to
Site knowledge accumulates quietly. Where the spare liners live, which alarm zone needs care, which room is booked on Thursdays, which surface must not be treated with the usual product. None of it is in the scope document because nobody thought to write it there. When the attendee changes, that knowledge leaves with them and the new person rebuilds it slowly, usually while you notice small things going wrong.
This is why a provider's turnover rate matters more to you than it looks. You are not paying for the company's stability in the abstract; you are paying for the specific person who will be in your building each week. Ask how long the cleaner they intend to assign has been with them, and how many different people have serviced their comparable sites over the last year.
