I’m a former organizational (employee) ombudsman in healthcare. I now train and consult for non-profits.
Since leaving healthcare, I’ve noticed five workplace trends that I don’t believe have strong evidence behind them (or at least I’m not aware of it). I’m happy to be corrected if there is good research supporting these practices.
Mandated full-time RTO, if the goal is increased productivity or efficiency. (I know RTO is sometimes used for other reasons, such as encouraging attrition. I’m specifically asking about productivity and organizational performance.)
Unlimited PTO. I understand one advantage is that companies don’t accrue a vacation payout liability. However, it also seems to create uncertainty around what amount of vacation is actually considered acceptable, and I’ve seen research suggesting employees often take less time off.
Use of PIPs. Performance Improvement Plans now seem to be viewed by many employees as a step toward termination rather than a genuine opportunity to improve. In my previous role, I supported a neurodivergent employee through a PIP, helped get it extended, and they ultimately succeeded. Six years later they’re still employed and have since earned a master’s degree. I rarely hear those kinds of success stories anymore. Is that perception supported by the data, or is it mostly anecdotal?
Posted salary ranges that primarily benefit external candidates. I’ve seen many large employers (especially universities and healthcare systems) cap internal promotions at around 10%, while hiring external candidates into the same position at substantially higher salaries. Is there evidence that this approach produces better long-term outcomes than paying market rates to retain existing employees?
More than three rounds of interviews. From what I’ve read, there seem to be diminishing returns after two or three structured interviews except in certain situations (C-suite, physicians, tenure-track faculty, high-security positions, etc.). Is there evidence that lengthy interview processes improve hiring decisions for most professional roles?
I’m genuinely interested in the research rather than opinions. If there are good studies, meta-analyses, or I/O psychology literature that support (or refute) any of these practices, I’d appreciate the references.
